Re: Try this Re: Can't connect to MySQL with Cocoon 2
Hi, I am a fellow applier of Cocoon and MySQL. If you haven't solved it yet perhaps you may want to attach you mysql connection files, excerpts from the tomcat/logs.localhost*.txt for the error, versions, etc. I can look at it tomorrow morning. I had originally modified Avalon Pool connection(still using it) to get it to work with jvm 1.4 and MySQL. I am in the middle of getting the latest HEAD of Cocoon2 and avalon to work with the jvm and MySQL and trying to determine the problem there so might as well look at more of the same:) -Roger - Original Message - From: Arda Balci [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, May 09, 2002 11:02 AM Subject: Re: Try this Re: Can't connect to MySQL with Cocoon 2 I have a mysql connection problem: I configured cocoon.xconf, web.xml, and the xml content file, correctly as stated in the user docs,and as stated in the mailing list and double checked the files.

From: Daniel Vogelheim [mailto:[EMAIL PROTECTED]] Hello, You can install *headless X* (Xvfb) which is BTW faster than X.

Try this Re: Can't connect to MySQL with Cocoon 2
Daniel, Maybe I don't understand using databases with Cocoon after all. Are you using the database for logging? If not why did you define it in the jdbc block in the xconf file that way (as a logger)? Here is what I did to get it working (and I got these steps from the userdocs) 1) I put the mysql.jar file (which contains the mysql jdbc driver) in the tomcat4.01/lib directory. I vaguely remember having trouble when it was in the cocoon/WEB-INF/lib ... and once it started working I did not complain or spend additional time researching why it failed down in the lower directory. 2) I created a jdbc block in the cocoon.xconf file as follows ... jdbc name=mysql_pool pool-controller min=5 max=10/ dburljdbc:mysql://localhost/mydb/dburl userroot/user password/password /jdbc where ... mydb is the (very creative) name I chose for the database. 3) In the webapps/cocoon/WEB-INF directory ... I put the following in the web.xml file ... init-param param-nameload-class/param-name param-value !-- For MySQL on localhost-- org.gjt.mm.mysql.Driver !-- For JDBC-ODBC Bridge: -- sun.jdbc.odbc.JdbcOdbcDriver !-- For parent ComponentManager sample: org.apache.cocoon.samples.parentcm.Configurator -- /param-value /init-param 4) Finally I use the mysql_pool, as follows In the sitemap ... within the map:pipelinethe transformer looks like this map:transform type=sql map:parameter name=use-connection value=mysql_pool/ 5) In the content source file for the map:generator component I have this code ... (note there is more than just this code in the file. In the interest of space I am just showing the sql stuff) execute-query xmlns=http://apache.org/cocoon/SQL/2.0; query select * from emp where name='Conrad' /query /execute-query (of course there was a table named emp in mydb ... and it was set up correctly and I made sure there was data in that table -- I verified everything from the mysql console) ... then I fired up Cocoon (and prayed for a miracle!!). The C2 gods must have been pleased with me that day ... because ... it worked!!! I, however, did not have a bottle of champagne when I saw the data in my browser ... but it worked!! and I was not going to complain about format etc etc. That is the topic for another bottle of champagne :) Hope that helps Conrad [EMAIL PROTECTED] wrote: Hello all, I have a problem connecting to a MySQL database with Cocoon.

Re: Can't connect to MySQL with Cocoon 2
Hello Zack, Apparently a lot of people have been having trouble getting mySQL+C2 to work with the 1.4 JDK. I'd try 1.3 and see if that helps any. HTH. Thanks; that solves it. With IBM's JDK 1.3 my setup worked right away. The reason I used JDK 1.4 is because I don't run X. According to the FAQ, only JDK 1.4 can run in 'headless' mode, and indeed with JDK 1.3 Cocoon doesn't start unless I also run X. So my problem is solved for now, but I'm hoping for a better long-term solution (i.e., no X, and still MySQL access). Thanks everyone!

The last message gets repeated over and over again. The query looks
OK, but apparently something goes wrong, and Cocoon just tries again.
That doesn't really make sense to me, since what ever is going wrong,
will be just as wrong 5s later. Anyway... so something is wrong with
the SQL connection. But what?
